GEORGE. W. GIBBS, OF NEW YORK, N. Y.

TIME-RECORDER.

To all whom it may concern Be it known that I, Grnonon V. GIBBS, a citizen of the United States, and resident of the borough of Brooklyn, in the city and State of New York, have invented a new and useful Improvement in Time-Recorders of which the following is a specification.

This invention relates to a time recording device, with the general object of providing a recorder which will furnish an accurate daily record of the working hours of. em ployees and enable the employer to readily check up their coming and going.

Devices of this character now on the market are in general expensive, large and cum bersome, of intricate mechanism and only adapted to be used when in an upright position.

An object of this invention is to provide a time recorder which will be low in cost, simple in construction and of a convenient size and weight so that it will occupy a minimum of space and may be readily moved from place to place and operated either in a vertical or horizontal position.

Other objects are to provide certain improvements in the form, construction and arrangement of the several parts whereby the above mentioned objects may be effectively carried out.

A practical embodiment of my invention is represented in the accompanying drawings, in which Figure 1 represents a top plan view of the complete device, Fig. 2 represents a side elevation of the same, Fig. 3 represents a horizontal section taken in the plane of the line AA of Fig. 2, looking in the direction of the arrows, Fig. 4: represents a vertical section taken in the plane of the line B-B of Fig. 1, looking in the direction of the arrows, Fig. 5 represents in side elevation a printing key, such as may be used in the operation of the device, and Fig. 6 represents a series of imprints such as may be used on the printing surfaces of printing keys similar to the one shown in Fig. 5.

The device comprises in general an exterior box of any desired or convenient shape, the one shown in the present instance being substantially rectangular in plan view and relatively fiat or low. This box may be made of brass or other suitable material and comprises a bottom 1, sides 2, a back 3, a front 4, and a top 5, firmly united to form Specification of Letters Patent.

a strong receptacle or case. The top 5 is hinged as at 6, to the back 3 so that it may be readily opened, and is further provided with a lock 7 adapted to engage a projection 8 on the front 1. Any of the well known forms of lock may be used for this purpose. Inside of this box and resting on the bottom 1 are four uprights 9, 10, 11, 12, which support platforms 13 on which is se curely mounted the clock mechanism 14. Any convenient or well known clock mech anism may be used. Above the clock mechanism 1 1 and resting on top of the uprights 9, 10, 11, 12, is a plate 15, through which uprights 9 and 11 extend to form knobs by which the clock mechanism and inclosing plates 13, 15, may be lifted out of the surrounding box or case.

The hour arbor or pintle 16 of the clock 14 extends through a hole 17 in the plate 15 and is provided with a screw threaded at its extremity. To the arbor 16 is fixedly attached, against rotation, a disk 18 lying in a plane slightly below the plane of the plate 15.

A circular dial 19, of cardboard or other suitable material, together with a carbon paper 20 of similar size and shape superposed thereon, are secured upon the disk 18 by means of a nut 21 engaging the screw threaded end of the arbor 16, which passes through centrally disposed holes in the dial and carbon paper.

It will be seen that the above arrangement is such that the dial and carbon paper travel with the disk at the speed of the hour arbor.

The face of the dial 19 is numbered and divided clock-like into twelve equal paths which are separated by radial lines and represent the hours of the day; and each hour is divided by four radial lines into quarter hours. The dial is further divided by a se ries of concentric circles, the number varying with the number of printing keys to be used. The carbon paper 20 is likewise di vided into concentric circular bands to correspond to dial 19, and these bands may be of different colors.

The top 5 of the case has a series of holes or pockets 22 of a size to accommodate the printing keys 23, which holes may vary in number, and location, though there will generally be a hole arranged to register with each different colored band of the carbon paper.

The printing keys may have on their ends letters, numbers or any configuration desired.

In operation, the clock mechanism let will rotate the dial 19 and carbon paper 20 at the speed of the hour arbor 16, thus making a complete revolution in twelve hours. hen a key is inserted in one of the pockets 22 the pressure of the key on the carbon paper 20 will transfer to the dial 19 the impression of the character on the key thus leaving a record on the dial which will show at what time of the day the impression was made.

By the use of different colored carbon paper and different configurations or characters on the keys, the records of a considerable number of men can be kept on a very small machine.

The device may be provided with any suitable means for attaching it to a support in either a vertical or horizontal position.

It will be understood that various changes may be made in the form, construction and arrangement of the several parts without departing from. the spirit and scope of my adapted to receive and transfer to the dial.

the impresses of the keys in different colors at different radial locations.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two witnesses, this eighth day of November, 1912.

GEORGE .V. GIBBS.
